Abstract

The Learning to Reason framework combines the study of Learning andReasoning into a single task. Within it, learning is donespecifically for the purpose of reasoning with the learned knowledge.Computational considerations show that this is a useful paradigm; insome cases learning and reasoning problems that are intractable whenstudied separately become tractable when performed as a task ofLearning to Reason.In this paper we study Learning to Reason problems where theinteraction with the world supplies the learner only partialinformation in the form of partial assignments. Several naturalinterpretations of partial assignments are considered and learning andreasoning algorithms using these are developed. The results presented exhibit a tradeoff betweenlearnability, the strength of the oracles used in the interface, and the range ofreasoning queries the learner is guaranteed to answer correctly.
